"In a social bookmarking system, users store lists of Internet resources that they find useful. These lists are either accessible to the public or a specific network, and other people with similar interests can view the links by category, tags, or even randomly. Some allow for privacy on a per-bookmark basis.
They also categorize their resources by the use of informally assigned, user-defined keywords or tags (see folksonomy). Most social bookmarking services allow users to search for bookmarks which are associated with given "tags", and rank the resources by the number of users which have bookmarked them. Many social bookmarking services also have implemented algorithms to draw inferences from the tag keywords that are assigned to resources by examining the clustering of particular keywords, and the relation of keywords to one another.
Its increasing popularity and competition have extended the services to offer more than just sharing bookmarks, such as rating, commenting, the ability to import and export, add notes, reviews, email links, automatic notification, feed subscription, web annotation, create groups and social networks."
What this means for us:
We can have our favorites travel with us wherever we go regardless of computer
We can create a network of shared bookmarks, or tags, among friends, colleagues, etc.
We will gain access to sites that are relevant, or at least popular.
